混交林中树木形态特征、食物特性与天牛选择行为的研究

A Study of Tree Morphology,Food Characters and Selection Behavior of Longicorns in Mixed Forests

通过观察、测定、分析得到混交林中影响光肩星天牛成虫行为的树木外部形态特征主要有树皮的粗糙程度、叶片的质地、大小、上下表皮毛、腺体、光滑程度、嫩枝毛、腺体、软硬度 ;另外食物特性也影响天牛选择行为和种群动态。

Through observation,analysis and measurement,the morphological features of trees effecting the behaviors of longicorns in mixed forests were found out,i.e.,the rough- ness of the tree bark,leaf texture,seize,epidemal hair,gland smoothness,hair of tender branches,hardness etc.Moreover,the selection behaviors of longicorns and population dy- namics were also effected by food characters.
